Answer 1

If you has a dynamic array
$first = $array[0]['latitude'];
$last = $array[count($array)-1]['latitude'];
For you example you can just use this code
$first = $array[0]['latitude'];
$last = $array[1]['latitude'];

Answer 2

if you want a general and reusable way define this function:
function array_pluck ($toPluck, $arr) {
return array_map(function ($item) use ($toPluck) {
return $item[$toPluck];
}, $arr);
}
then
$latitudes = array_pluck("latitude", $myarrays);

Answer 3

Use a foreach loop.
foreach($arrays as $array) {
echo $array['latitude'];
echo $array['longitude'];
}
